Wall-hung basins are one of the smallest line items in a fit-out bill of quantities and one of the most expensive to change once the rooms are tiled. A basin that looks identical on paper can differ from vendor to vendor in clay body, glaze thickness and fixing method, and in whether the matching water closet and bidet are still being made years after handover. This guide sets out the checks that separate a real match from a look-alike when comparing suppliers of Wall Hung Ceramic Basin 1004B, Modern Wall Mount Bathroom Sink for hotels, apartments and public washrooms.

Model 1004B is a wall-mounted vitreous ceramic basin with a trapezoid outline and a glossy glaze, fixed to the wall through its back panel rather than a cabinet or a pedestal. The published size is 510×420×380 mm, and the bowl ships with a tap hole for a single faucet. Because there is no floor-standing support, the whole unit reads as a floating plane, which is exactly why designers choose it for compact guest bathrooms: the floor under the basin stays clear, so mopping reaches the wall line and there is no grout perimeter to trap moisture.

Two practical details decide whether 1004B works on your job. First, back-panel fixing means the substrate has to carry the load: solid brick, a structural stud wall with nogging, or an engineered frame behind the tiles. Second, the faucet position is fixed by the pre-drilled hole, so the spout reach and the trap outlet have to be set out before the first wall is closed up. Ask every supplier to confirm rough-in dimensions against their current technical data sheet rather than relying on a catalogue PDF that may lag the production drawing.

Ask for vitreous china, and ask what that means in the supplier's quality control. A dense, fully vitrified body absorbs very little water, which is what keeps the basin from taking on odours in a humid bathroom. The glaze is the second half of the story: 1004B is described as having a dense glazed layer that resists water stain and limescale, and that claim matters commercially because descaling frequency is an operating cost, not a cosmetic one.

When you compare quotes, ask each supplier three questions in writing: what water-absorption range does the body meet; is the glaze applied to the interior of the overflow channel as well as the visible faces; and which cleaning agents are excluded from the finish warranty. Suppliers who answer with test references are usually a safer bet than suppliers who answer with adjectives.

A single basin is easy to source. A matching set across a whole floor of guest bathrooms is harder, and this is where supplier depth shows. The 1004 series is a coordinated family: Washdown One Piece Toilet 1004A shares the same square-rounded silhouette and glaze, and it supports both P-trap wall drainage and S-trap floor drainage, which gives the same model flexibility across different pipeline layouts in a multi-storey building. The Wall Hung Bidet 1004F covers projects specifying separate hygiene fixtures, and the freestanding 1004S stand basin lets you use the same design language in bathrooms where a wall fix is not feasible.

Compare suppliers on how many pieces of that family they actually make. If one vendor supplies basins and subcontracts the water closets, glaze colour and batch consistency between the two will drift, and you will notice it at handover when the toilet reads slightly warmer than the basin under the same lighting.

A good supplier will tell you when 1004B is not the right model, so it is worth knowing the neighbours in the range before you ask. Wall Hung Ceramic Basin 1051B measures 400×380×450 mm with a softer curved profile, and its narrower footprint suits tight guest WCs and boutique hotel rooms where counter depth is scarce. Wall Hung Ceramic Basin 1050WB at 495×440×390 mm adds a gold line detail for suites and reception washrooms where the brief asks for a decorative accent. For staff corridors, plant rooms and public washrooms where hard wear matters more than the design line, Wall Hung Basin 1038WB is the plainer, serviceable option in the same wall-mounted family.

If a supplier only offers one wall-hung model and cannot discuss substitutes, you are buying a product, not a specification service.

Ceramics rarely arrive alone. On most hospitality and residential jobs they land alongside vanities, mirrors, shower systems, wall finishes and lighting, and every separate vendor is another set of drawings to reconcile. A Bathroom Sanitary Fixtures range that sits inside a wider catalogue means one party owns the schedule for all of it.

That structure changes what you compare. Instead of matching a unit price per basin, you compare how one supplier sequences ceramics against joinery and tiling, and who answers when a tap hole needs relocating on site. Where the brief covers more than catalogue items, Turnkey Interior Project Solutions is how SANTERSON supplies villa, hospitality and office scopes from a single manufacturer, with custom and OEM production, freight by sea, air and rail with door-to-door delivery, and installation and after-sales support.

Commercial orders rarely stay on standard specification for long. Contract administrators substitute colours, designers change faucet heights, and a project may need the same basin in several different configurations across room types. A manufacturer that handles custom and OEM work in-house can adjust finishes and configuration against your drawings; a trading company passes the request on and accepts whatever comes back. Whichever route you choose, require a signed physical sample before mass production starts, and keep that sample on site as the reference for glaze colour and gloss level.

• Confirm rough-in, trap type and faucet reach against the current technical drawing, not the marketing sheet.
• Verify the wall build-up behind the tiles can carry a back-panel wall fix, and get the fixing detail in writing.
• Order one full 1004 series set, basin plus water closet, to check glaze match under your own lighting.
• Ask for the cleaning-agent exclusions that sit behind any finish warranty claim.
• Agree packing and pallet configuration with the supplier, and hold back spare units against transit breakage, because a replacement basin arriving late is a scheduling problem before it is a cost one.
• Confirm who handles installation queries after delivery and how replacements are supplied.

Comparing suppliers of Wall Hung Ceramic Basin 1004B comes down to three tests: does the body and glaze evidence hold up, is the whole 1004 series made under one roof, and how does the vendor behave when a specification changes mid-job. A supplier who passes all three is usually worth the extra paperwork, because the saving on a single basin is small next to the cost of opening a tiled wall.
